[CostModel][X86] Add CostKinds handling for fcmp ops

This was achieved with an updated version of the 'cost-tables vs llvm-mca' script D103695 (although it still struggles with avx512 predicate numbers which had to be done manually)

SSE numbers are still too low for FCMP_ONE/FCMP_UEQ cases which expand to a more complex sequence than the existing 'ExtraCost' system can manage.
